Abstract

The utility model relates to a compound needle of a computerized flat knitting machine, which comprises an assistant needle provided with a needle hook at the front end, and a main needle provided with a sliding groove, wherein the assistant needle is freely advanced and retreated in the sliding groove (12) of the main needle. The utility model is characterized in that the main needle is in a long-strip flat shape, the head part of the main needle is provided with a pointed cone part (13), an upper end surface of the sliding groove is sealed by the pointed cone part, the upper part of the main needle is provided with an inner groove (14) along the side surface, and the inner groove (14) is communicated with the sliding groove (12). The compound needle disclosed by the utility model can effectively avoid the situation that the needle is broken when the head part of the compound needle is inserted into a thread in the process of bottom rising and ensure the paying off success ratio of the compound needle.

Description

The compound needle of computer flat knitting machine

Technical field

The utility model belongs to the computer flat knitting machine technical field, is specifically related to be used for main pin of having of knitting machine and secondary pin, pinhock is carried out the compound needle of switch by the relative motion of main pin and secondary pin.

Background technology

In existing Computerized flat knitting machine; the radical that constitutes the stocking yarn of a coil in braided fabric is most; using compound needle to carry out several repeats; adopt the open top formula because play bottom plate combined pin top in the prior art more; the compound needle of open top formula is in playing end process; because playing the rising of base plate is easy to be inserted in the top slot of compound needle playing bottom line; cause compound needle head cracking; bad pin situation such as bending; and playing base plate regular meeting in the prior art, unwrapping wire to occur incomplete, influenced a base plate and brought into play better.

Summary of the invention

In order to solve the defective that compound needle ftractures easily at the bottom of above-mentioned, the utility model provides a kind of compound needle, and it can effectively have been avoided, and the compound needle head is inserted into line in the end process, causes the situation of bad pin, and guarantees the success rate of compound needle unwrapping wire.

For realizing goal of the invention, the technical scheme that the utility model adopted is:

The compound needle of computer flat knitting machine, be included in the main pin that front end has the secondary pin of pinhock and has sliding tray, secondary pin is freely advanced and retreat in the sliding tray of main pin, it is characterized in that main pin is rectangular flat-shaped, head has pointed cone portion, the upper end of sliding tray has inner groovy on main pin top along the side by the sealing of pointed cone portion, and inner groovy communicates with sliding tray.The main pin of the utility model compound needle is thin prolate type strip, and head is semiclosed, and secondary pin is the lengthy motion picture shape, and the end places in female needle tray and can move up and down for colluding type, because head is the taper sealing, coil withdraws from easily and don't the situation that tuck damages pin can occur.

Further the scheme of optimizing is, above-mentioned pointed cone portion and axial side direction chamfering are α, and α is 30 °～45 °.This chamfering can be walked compound needle assurance line when rising easily on the limit

Further again, the utility model master pin top has the downward inclined-plane that moves back in the side of inner groovy, and this moves back the main relatively needle shaft in inclined-plane to being the β angle, and β is 30 °～40 °.Move back the smooth fiber of not hanging of chamfered surface, this moves back the inclined-plane and helps secondary pin and can perfection collude line and unwrapping wire.

Compound needle compared to existing technology, the utility model compound needle beneficial effect is that this compound needle can carry out the knocking over of coil more swimmingly, and solved domestic and international great majority and played the easy to crack and incomplete practical problem of unwrapping wire of bottom plate combined needle section, make the straight-bar machines total quality more stable, the cloth tablet quality is higher.

Among the figure: 1 is main pin, and 12 is sliding tray, and 13 is pointed cone portion, and 14 is inner groovy, and 15 for moving back the inclined-plane, and 16 is fixed part, and 2 is secondary pin, and 21 is pinhock, and 22 is control part.

The specific embodiment

Below the utility model is described in further detail by specific embodiment.

Embodiment 1

Shown in Fig. 1-11 was, the compound needle of the utility model computer flat knitting machine comprised main pin 1 and secondary pin 2, and main pin is thin prolate type strip, and secondary pin is an elongated plate.

Secondary pin as Figure 1-3, secondary pin is extended with pinhock at front end, smooth surface, this structure coil after catching on coil is difficult for running out of, good stability, and be easy to slide up and down in main pin.Secondary Aculeata is provided with control part 22, and control part 22 is perpendicular to secondary pin dial, and it is up and down to control secondary pin.

Main pin profile such as Fig. 5-11 are depicted as thin prolate type strip, main needle set has the sliding tray 12 that holds secondary pin, secondary pin is freely advanced and retreat in the sliding tray 12 of main pin, main needle section has pointed cone portion 13, the upper end of sliding tray is sealed by pointed cone portion, have inner groovy 14 along the side on main pin top, inner groovy 14 communicates with sliding tray 12.The main pin profile in fluting back is slotted its top, back as shown in figure 10 as shown in Figure 6, and it stays certain surplus to make its top not open-minded topmost, guarantees that the tip position of main pin seals.

Main needle point tapering 13 is α with axial side direction chamfering, and α is 30 °～45 ° shown in Figure 10, and this chamfering makes compound needle guarantee that when rising the line edge that can keep to the side easily slips.Main pin top has the downward inclined-plane 15 that moves back in the side of inner groovy 14, shown in Figure 11, and the smooth fiber of not hanging of chamfered surface, this moves back the main relatively needle shaft in inclined-plane to being the β angle, and the β optimized angle is 30 °～40 °, guarantees that secondary pin can perfection collude line and unwrapping wire.Main Aculeata has fixed part 16 as shown in Figure 7, and fixed part 16 is used for fixing the position of compound needle.

The utility model compound needle operation principle is as follows:

Secondary pin 2 is placed in main pin 2, it can be up and down in sliding tray, and main pin has been fixed on the base plate by fixed part 16, and secondary pin moves up and down by the secondary pin of control part 22 controls in main pin, under the normal condition, secondary pin 2 is in last raise-position, and crochet hook is in main pin inside fully, when needs play the end, playing base plate rises, colluding line position when arrival is, secondary pin 2 is movable downwards, and pinhock exposes main pin and catches on coil.Secondary pin 2 moves up during unwrapping wire, and coil is blocked under the effect of moving back line inclined-plane 14, thereby coil is deviate from from the pinhock of secondary pin.

Above with reference to the description of accompanying drawing to being illustrated property of the utility model; just preferred embodiment shown in the accompanying drawing; those of ordinary skill in the art should be understood that; need not creative mental labour according to the technical solution of the utility model and technical conceive and make other various corresponding conversion scheme; under the situation that does not break away from the utility model design aim, all belong to the scope that the utility model is protected.
